Cassini approach movie of Jupiter - Tracking the Great Red Spot
Processed with Gimp to see more details - cleaned, enlarged x2, rotated (North is up). One frame for (almost) every Jovian rotation, aligned on the great red spot. As the spacecraft made its approach, the resolution of the frames increases from start to finish. A different processing with the alignment on the right side of the disk can be seen here: https://goo.gl/47P59z The delay between frames is 110ms. https://www.flickr.com/photos/alex-is-solaris/29500757623/in/dateposted-public/
